Problems solved by technology

Therefore, when the addition amount of the additive is increased, there is a problem that the weight of the flame-retardant insulated wire as a whole increases, and when an aluminum-based material is used as a conductor, the flame-retardant insulated wire has simultaneously flame retardancy, stretchability, Abrasion resistance, long-term heat resistance and similar properties are difficult
In addition, when a large amount of additives are mixed to improve the above-mentioned properties, a problem arises that the mixing and weight reduction are contradictory

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0017] see figure 1 , the embodiment of the present invention includes: an insulated flame retardant wire, including: a conductor 1, a first flame retardant layer 2, an insulating layer 3, a luminous layer 4 and a second flame retardant layer 5, the conductor 1 and the first flame retardant layer Flame-retardant layer 2 is connected, and the material of described conductor 1 is copper, because the silver wire is the best, but the cost is too high, followed by copper wire, which is the most used wire, and aluminum wire, although not as good as copper wire line, but the cost is low, so copper with moderate cost and strong electrical conductivity is...

Abstract

The invention discloses an insulation flame-retardant wire. The insulation flame-retardant wire comprises conductors, first flame-retardant layers, an insulation layer, a noctilucence layer and a second flame-retardant layer, wherein the conductors are connected with the first flame-retardant layers, the first flame-retardant layers are connected with the insulation layer, the insulation layer is connected with the noctilucence layer, and the noctilucence layer is connected with the second flame-retardant layer. Through such a mode, the insulation flame-retardant wire provided by the invention is light in weight, can satisfy the requirements for flame retardation, wear resistance and long-term heat resistance at the same time, and can prevent an accident that the combustion of an inner line ignites a neighboring wire.

Description

technical field [0001] The invention relates to the field of insulation, in particular to an insulated flame-retardant wire. Background technique [0002] Hitherto, as flame-retardant insulated electric wires wired in automobiles, electric wires obtained by covering copper wires with a resin composition using polyvinyl chloride resin as a base resin are often used. Polyvinyl chloride resin has excellent material properties such as flame retardancy and mechanical properties. However, when polyvinyl chloride resins are burned at the time of incineration, car fires or the like, environmental problems have become increasingly prominent due to generation of harmful gases such as halogen-based gases. [0003] Therefore, recently, as a halogen-free resin composition, polyolefin-based resins and olefin-based resins or styrene-based resins have been developed as base resins. In order to form a halogen-free insulating covering, a large amount of additives is necessarily required in ...
